In 3–5 sentences, summarize the rotations that carry a regular pentagon onto itself.

Answer 1

The rotations that carry a regular pentagon onto itself are achieved by rotating the pentagon by a multiple of $\frac{2\pi}{5}$ radians around its center. There are five possible rotations in total: a rotation of $\frac{2\pi}{5}$ radians, $\frac{4\pi}{5}$ radians, $\frac{6\pi}{5}$ radians, $\frac{8\pi}{5}$ radians, and a full rotation of $2\pi$ radians. Each of these rotations preserves the shape and orientation of the pentagon.
